In the removal of spots from various fabrics, cloth or the like, the conventional method employed by the average individual is to apply cleaning fluid to a clean cloth which is then The dirt is thereby partially dissolved, partly absorbed by the cleaning cloth and partly rubbed into the soiled material. This method tends to leave rings on the material being cleaned formed by the dissolved dirt rubbed into a larger area of the material. This disadvantageous method is avoided by the present invention which provides a means not only for applying cleaning fluid to the material, but for thoroughly washing a small area of the material by forcing relatively large amounts of cleaning fluid through it, thus washing out the spot in substantially the same manner as dry cleaning machines employed by professional cleaners.
It is, therefore, an object of the present invention to provide a simple means for washing a small area of soiled material in such a manner that the soiled portion of the material is properly cleaned such as is achieved by professional cleaners.
A further object of the invention is to provide a simple method for cleaning small areas of soiled material wherein the accessories required are of simple nature and are readily operated by the average individual.
A still further object of the present invention is to provide a compact simple cleaning jar or container providing facilities for effecting cleaning of this character and which may be made available as a complete cleaning unit or as an accessory usable in conjunction with an average container for cleaning fluid.
A still further object of the invention is to provide a cleaning means which due to its simple character may be made available at comparatively low cost.
With these and other objects in view, the invention generally comprises a container designed to receive cleaning fluid, an insert therefor over which the soiled material is designed to be disposed and a syringe applicable to the material on the insert for freely passing cleaning fluid through the soiled material. This combination may include an insert of such character as to dispose the material slightly below the level of the cleaning fluid carried therein to permit back and forth movement of the fluid through the soiled portion of the material. It may also be formed as an accessory usable in conjunction with the conventional cleaning fluid container, wherein the insert takes the form of a permanent portion of the accessory. Preferably the cleaning fluid container of the present invention includes a cover member usable as a surface for sup- 9 Claims. (Cl. 68-213) porting the cleaned area of the material. to permit final rubbing and drying of the said area.
The invention will be fully understood by reference to the following detailed specification taken in conjunction with the accompanying drawings.
In the drawings,
Figure l is a longitudinal section taken through a syringe-like bulb formed according to the present invention. Figure la is a side elevation of a disc like filter element. Figure 1b is 'a longitudinal section taken through a container designed co-operatively to employ the elements of Figure 1 and 1a.
Figs. 2, 3 and 4 are schematic views of the steps followed in cleaning, the first two views being in longitudinal section.
Fig. 5 is a longitudinal section taken through an alternative form of syringe including an air vent tube, the structure being particularly designed for cleaning heavy materials.
Fig. 6 is a longitudinal section taken through a cleaning combination wherein the container is designed particularly as an accessory filled from the conventional container of cleaning fluid; and
Fig. 7 is a longitudinal section taken through a cleaning combination including a container structure having a support for the material to be cleaned which is disposed inwardly of the container to a substantial degree to permit submerging the soiled area of the material directly in the cleaning fluid.
Referring to the drawings, and particularly to Figs. 1 to 4, A indicates a cleaning combination which is made up of a container l8 and a syringe II. The container preferably is formed with a substantially large inlet opening l2 and is designed to carry within the opening an insert 13 which is designed to support the material to be cleaned such, for instance, as is clearly illustrated in Fig. 3. r
The insert is formed with a central opening l4 over which the soiled area of the goods is designed to be positioned, as shown in Fig. 3, de-
signed to be removed and removably supported in suitable manner such as by the ledge l5 formed within the neck of the container. The jar is readily closed by a suitable cover it which is preferably designed to perform the functions of a support for the material in the final step of the cleaning operation as will hereinafter appear. The syringe is of particular form as shown, having a lower base portion ll which is outwardly flared to form a suitable grip and through which pressure may be applied to effect a substantial seal between the bases of the syringe and the insert l3 when clamping the material therebetween. It is formed with a lower restricted opening it which opens into a cupped recess Hi. The cupped area is preferably substantially similar to the area of the opening l4.
In order to provide for an efficient cleaning operation so as to cause the fluid to pass through the soiled area of the material and to prevent spraying of the cleaning fluid through other portions of the material by capillary action, it is necessary to provide for an efficient seal between the support l3 and syringe as they clamp the area of the materia1 therebetween. This is effected by providing the concentric sealing rings 20 which efliciently clamp the material marginally of the soiled area of the material, thus to prevent the normal capillary action of the material when saturated with the cleaning fluid. In addition, a further seal is effected by forming the marginal edges of the base with an inward and downward taper 2|. This tapered portion, as shown particularly in Fig. 3, is designed in effect to wedge the material against the marginal edge of the insert [3. In this way, therefore, the efficient passage of the cleaning fluid through the soiled area of the material is provided for and the spraying of the fluid through the material beyond the area to be cleaned is largely prev nted.
To eifect a cleaning operation, the cover It is removed from the container and the insert 13 is also removed, thus to permit the prog'ection of the base of the syringe into the container as shown in Fig. 2, so that the syringe may be filled. Preferably, the body of the syringe is formed wide enough so that it will engage the neck of the container intermediate the ends of the syringe thereby to prevent the base of the syringe from passing down into the container directly adjacent to or touching the bottom thereof in order to prevent sucking up any sediment which might pOS- s'ibly :lie in the base of the container from a previous cleaning operation.
In this way, therefore, the cleaning fluid is sucked into the syringe. The syringe is then removed from the container and the insert 13 replaced. The material to be cleaned is then laid over the top of the container and the soiled area disposed over the opening l4 therein. The syringe then may be placed in the position shown in Fig. 3, pressure applied thereto preferably through the grip provided at the base so as to seal the soiled area of the cloth firmly between the insert and the base of the syringe whereupon the fluid in the syringe is caused to be forced through the soiled material. The result is that the dirt contained in the soiled area is dissolved and washed away. Preferably the soiled side of the material is turn d downwardly towards the opening 24 of the insert so that the dirt as it is dissolved is caused to wash away without being passed through the unsoiled or less soiled portion of the material.
The cleaning fluid carried in the container may, in the course of time, become contaminated although where dirt or foreign material passes into the fluid it will often form as a sediment in the bottom and, therefore, this will not affect cleaning operations. In this case, however, I prefer to employ a filter which may take the form of a disc-like element 22 which may be disposed to lie upon the insert i3 so that the cleaning fluid as it passes through the material with a clean cloth until the dampened area is dry. In this manner, therefore, a spot may be efficiently cleaned from the material and rings and the like which are usually left in average manual cleaning operations are avoided.
This method readily applies to light materials, but where particularly heavy materials are concerned which require a higher pressure in order to force the fluid efficiently through them, it may be desirable to provide a special form of syringe which will avoid overflow of the cleaning fluid in the case where a particularly good seal is not aifected between the base of the syringe, the material being cleaned and the support. Such a construction is illustrated in Fig. 5 wherein the syringe is of general formbut includes an air tube 23 which extends from the upper extremities of the interior of the syringe to open upon an annular recess 26 disposed between the concentric sealing rings 2'5 and 26. Thus, where sufficient pressure is not applied to the base of the syringe in order to effect an efficient seal the fluid within the syringe will not be forced therefrom under adequate pressure because of the escape of air through the air tube 23. Where, however, a substantial seal is effected between the material and the base of the syringe, there will be created in the annular recess 25 a pressure corresponding to the pressure under which the fluid is forced from the syringe so that due to the equalization of this pressure as between the annular recess 24 and the cupped recess. [9 of the syringe, the fluid passing through the material is very efflciently maintained from spraying into a larger area of the material.
In the alternative form shown in Fig. 6, the' container takes the form of an accessory which is usable in conjunction with the conventional cleaning fluid container. In this connection, the container is provided with the open dished mouth 21, the surface of the dished portion thereof forming a permanent portion of the top of the container and functioning as the support for the material in place of the removable insert, as described in connection with Figs. 1 to 4. A central opening '28 is provided for the passage of fluid while an opening 29 is provided in the upper extremity of the container which functions as a discharge opening for pouring back the contents of the container to the conventional cleaning fluid container. It also functions a an air vent to prevent the escape of air from the container during the cleaning-operation. In this case the container is preferably formed shallow so as to reduce the amount of fluid that may be used in any one cleaning operation. Moreover, the preparation is such that two methods of cleaning may be performed where required. On the one hand, and particularly in the case of thin materialftli container may be fllled to a level above the level of the opening '28 so that the soiled portion is immersed in the cleaning fluid and cleaning may be effected by sucking the fluid into the syringe and forcing it back out so as to cause it to pass back and forth through the material to eifect a thorough washing action. On the other hand, and particularly in the case of figured materials, the syringe maybe filled first and the cloth laid over the empty dished portion 2'! of the container with the soiled surface downwards and the fluid passed through it in the conventional manner as described in connection with Figs. 1 and 4.
The further alternative form is shown in Fig. 7 wherein the cleaning'combination includes'a container 30 which is formed with the deeply dished support 3| depending within the container and terminating at its lower end in an aperture 3la through which cleaning fluid may be caused to pass upon operation of the syringe; the support 3! is preferably formed as a connected part of the container. In this case, for instance, a metal container is illustrated wherein the dished portion 3! is rolled into engagement with the upper extremities of the container, which latter may be formed with screw thread 32 to permit the application of a removable cover in a practical manner.
In this case the structure is particularly designed for a thorough back and forth washing of the fluid through the material being cleaned such as in the manner described in connection with Fig. 6.
It will be apparent from the foregoing that by a combination of simple elements such as described, means is provided for thoroughly washing a small area of materials with cleaning fluid whereby to remove the soil efliciently and in a simple practical operation.
